MAO-A (Ki = 4.2 μM); MAO-B (Ki = 46 μM)

|---|---|
| ln Vitro |
In human brain synaptosomes and human liver mitochondria, bifemelane inhibits MAO-A in a dose-dependent manner with Kis values of 4.2±0.2 and 14.1±0.7 μM, respectively [1]. In human brain synaptosomes and human liver mitochondria, bifemelane inhibits MAO-B activity in a dose-dependent manner with Kis values of 46.0±3.6 and 65.2±7.0 μM, respectively [1].
|
| ln Vivo |
Bifemelane (20-80 mg/kg; intraperitoneal injection) decreases exploratory activity in the open field test in a dose-dependent manner [3]. In the forced swim test, Bifemelane (20-80 mg/kg; intraperitoneal injection) shortens the immobility period [3], however the dose dependence is not evident and the maximum dosage of 20 mg/kg has been attained.

| Enzyme Assay |
4-(O-Benzylphenoxy)-N-methylbutylamine (Bifemelane, BP-N-methylbutylamine), a new psychotropic drug, was found to inhibit monoamine oxidase (MAO) in human brain synaptosomes. It inhibited type A MAO (MAO-A) competitively and type B (MAO-B) noncompetitively. BP-N-methylbutylamine had a much higher affinity to MAO-A than an amine substrate, kynuramine, and it was a more potent inhibitor of MAO-A than of MAO-B. The Ki values of MAO-A and -B were determined to be 4.20 and 46.0 microM, respectively, while the Km values of MAO-A and -B with kynuramine were 44.1 and 90.0 microM, respectively. The inhibition of MAO-A and -B by BP-N-methylbutylamine was found to be reversible by dialysis of the incubation mixture. MAO-A in human placental and liver mitochondria and in a rat clonal pheochromocytoma cell line, PC12h, was inhibited competitively by BP-N-methylbutylamine, while MAO-B in human liver mitochondria was inhibited noncompetitively, as in human brain synaptosomes. BP-N-methylbutylamine was not oxidized by MAO-A and -B. The effects of other BP-N-methylalkylamines, such as BP-N-methylethylamine, -propylamine, and -pentanylamine, on MAO activity were examined. BP-N-methylbutylamine was the most potent inhibitor of MAO-A, and BP-N-methylethylamine and -propylamine inhibited MAO-B competitively, whereas BP-N-methylbutylamine and -pentanylamine inhibited it noncompetitively. Inhibition of these BP-N-methylalkylamines on MAO-A and -B is discussed in relation to their chemical structure[1].

| Additional Infomation |
This study was designed with the rational aim of discussing the emerging antidepressant agents that are likely to bring positive landmark, tremendous improvement and significant impact to the management of patients with depression disorders. It also elaborates on the Agomelatine paradox vis-a-vis the other novel antidepressant agents. The emerging antidepressants are: selective monoamine oxidase inhibitors (MAOIs) such as bifemelane, pirlindole, toloxatone, selegiline, rasagiline and safinamide; serotonin-norepinephrine reuptake inhibitors (SNRIs) such as ansofaxine, nefopam and levomilnacipran; norepinephrine reuptake inhibitors (NRIs) such as Reboxetine, viloxazine, teniloxazine (also known as sulfoxazine or sufoxazine), and atomoxetine; Vilazodone (a serotonin 5-HT1A autoreceptor partial agonist with serotonin reuptake inhibition [SPARI]); Vortioxetine (a serotonin receptors antagonist with serotonin reuptake inhibition [SARI]); atypical antipsychotics such as olanzapine, quetiapine, risperidone, lurasidone, aripiprazole and brexpiprazole; N-methyl-d-aspartate (NMDA)-glutamatergic neurotransmission system blockers such as ketamine, CP-101,606 (traxoprodil), GLYX-13 (rapastinel), NRX-1074 (Apimostinel) and Riluzole. While Agomelatine (a melatonergic MT 1 and MT 2 receptors agonist and a selective serotonergic 5-HT 2B and 5-HT 2C receptors antagonist [MASSA]) remains a paradoxical agent that doesn't fit into any of the currently available classes of antidepressant agents and its pharmacological properties also deemed it unfit and inappropriate to be classified into another separate novel class of antidepressants contrary to the reports published in previous reference literatures. Lastly, this review remarkably advocates for the incorporation of the atypical antipsychotics and NMDA-glutamatergic ionoceptor blockers as new member classes of the antidepressant agents because of their clinically significant roles in the management of depression disorders[2].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
